How did the Sedition Act have been in conflict with the rights of Americans

The Sedition Act was opposed by minority Republicans, based on the argument that it violated First Amendment rights of Americans. It was based on the very same laws that England had, where it was illegal to criticize the king. The Sedition Act basically outlawed "conspiracies that oppose any measure of the government.", then later outlawed "false, malicious, scandalous writings of the government.".
